STEREOSCOPIC MEDALLION.

Specification of Letters Patent No.

To all whom it may concern Be it known that I, JOHN F. MASOHER, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Stereoscopic Medallion; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which I v Figure l, is a vertical transverse section of a medallion constructed after my invention, it being shown closed. Fig. 2, is an isometrical perspective view of the same, open or as it appears when used as a stereoscope. Fig. 3, is an external side elevation of the medallion closed.

Similar letters of reference in each of the several figures indicate corresponding parts.

This invention relates to an improvement in that description of medallion which has two lids or a hinged top and bottom constructed to receive daguerreotype or other pictures, said improvement serving at a very small cost to convert it into a stereoscope and also rendering it useful as a burning or sun glass and microscope, as will be hereafter shown.

The nature of my invention consists in constructing a medallion or locket with two inner or supplementary hinged lids, containing, each, a lens, (of about two inch focus,) and so arranged in relation to the outer lids or the bottom and top of the medallion that upon being opened and properly adjusted they shall cause the lenses to stand in front of, or opposite the outer lids containing the pictures and thereby convert the medallion into a stereoscope.

A, represents the frame of the medallion, made of ring, oval or other suitable shape.

B, B, are the outer lids, of the same, they are hinged to the frame A, as shown at a, a, these lids have the likenesses or pictures set in them and open in opposite directions to,

12,257, dated January 16, 1855.

and when the locket is closed'occupy the place shown in Fig. 1.

D, D, are the lenses, they are intended to be convex on their point sides when "the lids C, C, are open, instead of concave as shown:

in Fig. 1. These lenses are made of about two inches focus, and are arranged in the supplementary lids C, C, and when adjusted through the agency of the hinged lids, so as to stand in a proper relation to the lids B, B, cause a stereoscope to be-formed of the medallion, and the two likenesses or pictures, by binocular vision, apparently formed into a life like figure.

As the lenses D, D, are made of two inch focus they can be used either single or combined to great advantage, while arrangedas shown, for magnifying not only the pictures contained in the medallions or lockets, but

also bank notes. They can also be used in like manner as a burning or sun glass.

From the foregoing it is presumed the utility of this invention will be seen, it converting the ordinary medallion into a stereo containing two lenses; a patent having been granted to me for such an arrangement in 1853, therefore I do not claim the use of a supplementary lid as used in a daguerreotype case for such purpose, but

What I do claim as novel in this application and desire to secure by Letters Patent Constructing a medallion or locket A, B, B with two supplementary lids C, C, containing each a lensD, and arranged so as to fold within the picture lids B, B, and in such relation to the same that upon being opened and properly adjusted they shall cause the lenses to stand opposite said lids and thereby convert the medallion into a stereoscope, said arrangement also rendering the medallion useful as a. microscope and sun glass, substantially as herein described.
